This invention relates to a. dispensing carton having a hinged cover formed from an integral blank of cardboard and the like. More specifically, this invention relates to a dispensing carton for containing a roll of waxed paper from which the paper, is dispensed in web form and torn ofl. in suitable lengths as needed.

Generally speaking, the present invention contemplates a carton construction for dispensing or removing any article contained therein which can be grasped by the fingers by. opening a hinged cover. The carton is preferably formed from an integral blankwhich is suitably cut and scored to provide a container having front, rear, bottom and end walls and a cover integrally hinged to the container along a hinge of a novel construction. By virtue of this construction, the hinge is extremely flexible and facilitates'easy opening of the cover. .Also when the cover is res leased it has a tendency to fall back to closed position. To obtain thisfiexibility, the hinge is alternately scored and out along the hinge line to any desired ratio of respective lengths of the cut and scored portions.

Other further details of the invention will be apparent from the following specification and appended drawings.

Referring to the drawings,

Figure 1 is a perspective view of the dispensing carton made in accordance with the present invention showing the cover in closed and locked position,

Figure 2 is a perspective view of the dispensing carton showing the operation of tearing a length of paper web dispensed therefrom,

Figure 3 is a perspective view of the carton showing the hinged cover in open position,

Figure 4 is a plan view of the closed carton,

Figure 5 is an enlarged fragmental sectional view taken along lines 5-5 of Figure 3,

Figure 6 is-a iragmental plan view of a modification of the carton construction, and

Figure 7 is a iragmental sectional view taken on lines 1! of Figure 6.

Referring to the drawings, the carton I0 is preferably made from a single integral blank of cardboard and the like which is suitably cut,

'scored and glued to provide a front wall IS, a

rear wall 2, end wals 3, a bottom wall and a top panel 4. A cover II is integrally hinged to the top panel 4 along the hinge designated by numeral I2. The cover may be provided with a suitable cutting blade 9 ailixed to the free edge thereof for facilitating tearing the free end of a the carton. The front wall or the carton may be provided with a perforated score line 5 and an inverted U-shaped out line 6. The coveris provided with a cut score line I which forms a tongue portion that is insertable through the cut score line Ii into locking engagement as illustrated in Figure 1, thereby locking the cover when the carton is not in use. If desired, a portion of the front wall l3 may be removed along the score line 5 when the carton is to be used for facilitating insertion of the thumb within the carton for contacting the roll or other article contained therein. The construction of the carton so far described is fully disclosed in copendlng application Serial No. 370,388, filed December 16, 1940.

An important feature 01 the present invention resides in providing a hinge l2 for the cover of a novel construction which consists in forming the hinge from alternate cut and creased portions which are connected to each other. Referring to Figures 3 and 4, a hinge is provided having equally spaced semi-circular, curvilinear, triangular, or other suitably contoured cut portions indicated by numeral l5, so that an area is outlined extending beyond the hinge line defined by the straight creased score lines. These cut portions are connected by the spaced creased score lines I! which in the conventional hinge would be a continuous score line. Each of the ends of the hinge line is also preferably cut as indicated by numerals l6 for a substantial distance to give greater flexibility to the hinge. The alternate cut and creased portions of the hinge may be of any desired ratio 01' lengths so as to decrease the length of the creased portion'oi the hinge.

Hitherto, it has been customary to utilize merely a continuous creased score line for the hinge.

Obviously, when using a thick cardboard stock,

hinge to bulge outwardly when the cover is opened thereby further decreasing flexibility of the web 2!) from a roll of paper contained within the creased score portion on which hinging or the cover takes place is greatly reduced so that the resistance to fiexing oi the carton stock is greatly reduced, thereby providing greater flexibility in hinging the cover. Furthermore, the present hinge construction permits the opened cover upon'release to fall back readily into closed position as compared with the previous full line creased hinge which after opening resists closing because the fibers at the hinge must be reversely bent to their former position.

Various modifications may be made in actual carton constructions utilizing the present concept. The invention is not limited to any definite contour of the cut and creased portions of the hinge line. For example, Figures 6 and 7' illustrate a modification of the hinge line wherein the cut portions I! are reversely positioned in relation to each other and are connected by creased portions i4. Each of the ends of the hinge line is preferably cut for a substantial length as indicated by numeral It to provide still further flexibility of the hinge.

It is to be understood that the hinge construction is not necessarily limited to the specific carton construction herein disclosed. It may 'be utilized on any type of carton construction having a hinged cover therefor. The cover, for example, may be integrally hinged to any portion of an open ended container such as to the front or rear walls thereof, but the principle of hinged construction is utilized in a similar relation as in the specific embodiment herein disclosed. It is. therefore, intended to claim the invention herein disclosed as broadly as defined in the appended claims.

I claim:

l. A dispensing carton for receiving a roll of sheet material comprising a blank suitably scored and cut to provide a front, rear, bottom, end and top panels, said top panel having an integral portion hinged along a longitudinal line extending from one end of the panel to the other, said portion functioning as a cover portion, said hinge comprising regularly spaced out curvilinear score lines and creased score lines connecting said out score lines and said hinge being cut at each end thereof for a-substantial length along a continuous substantially zig-zag cut line extending at an acute angle at one portion thereof beyond said hinge line, and then in reverse direction at an acute angle to said hinge line.

2. A dispensing carton comprising a blank suitably scored and cut to provide a front, rear,

bottom, end and top panels, said top panel having an integral portion hinged along a longitudinal line extending from one end of the panel to the other, said portion functioning as a cover portion} said hinge comprising regularly spaced continuous cutand creased score lines, said out lines intersecting said creased lines along convergent lines and atlan acute angle to said creased lines so as to provide cut tongue portions extending beyond said creased lines whereby upon hinging said cover open the fibers of said blank will be instantly separated without sub- :tantial frictional engagement at the cut porions.

3. A dispensing carton comprising a blank suitably scored and cut to provide a front, rear, bottom, end and top panels, said top panel having an integral portion hinged along a longitudinal line extending from one end of the panel to the other, said portion functioning as a cover portion, said hinge comprising regularly spaced continuous .cut and creased score lines, said cut lines intersecting said creased lines along convergent lines and at an acute angle to said creased lines so as to provide cut tongue portions extending beyond said creased lines whereby upon hinging said cover open the fibers of said blank will be instantly separated without substantial frictional engagement at the cut portions and said hinge being cut at each end thereof for a substantial length along a continuous substantially zig-zag out line extending at an acute angle at one port m thereof beyond said hinge line, and then in reverse direction at an acute angle to said hinge line.

4. A dispensing carton comprising a blank suitably scored and cut to provide a front, rear, bottom, end and top panels, said top panel having an integral portion hinged along a longitudinal line extending from one end of the panel to the other, said portion functioning as a cover portion. said hinge comprising continuous alternately arranged semi-circular cuts and creased scores lines, said cut lines intersecting said creased. lines along convergent lines and at an acute angle to said creased lines so as to provide cut tongue portions extending beyond said creased lines whereby upon hinging said cover open the fibers of said blank will be instantly separated without substantial frictional engagement at the cut portions.
